Patented Dec. 8, 1914:.

To all whom it concern Be it known that I, ARTHUR L. SMITH, a citizen ofthe United States, residing at Okmulgce, in the county of Okmulgee andState of Oklahoma, have invented new and useful Improvements in Paint,of which the following is a specification.

This invention relates to improvements in coating compositions, and moreparticularly to a fire and rust proof mineral paint.

It is the object of this invention to pro vide a coatingcomposition orpaint particularly advantageous for coating metal structures which willprotect the metal work so coated from rust, will not crack or scale offfrom heat caused by fire or sun, and will also protect the metal workfrom the effects of steam. This coating composition or paint isparticularly advantageous for coating the fire boxes and boilers oflocomotives and other engines, as well as all other metal workssubjected to dampness and heat.

The paint comprising this invention is composed of thefollowingingredients in the following proportions: gallons coal tar, 5gallons asphalt-varnish, 5 gallons turpentine, 15 pounds groundasbestos, 6 pounds yellow ocher, 6 pounds Spanish whiting, 6 gallonswater, 10 pounds wood aslies (screened), 2 pounds crude caustic soc a. i

so as to blend as one material. Second. In another vessel mixturpentine, ground asbestos, yellow ocher and Spanish whiting to asmooth creamy like substance; add to first combination of coal tar,caustic soda and asphalt-varnish, all thoroughly blended. Third. In thethird vessel add water and wood ashes, mix thoroughly and add to othermixture, stirring until all are thoroughly mixed.

The coal ta rs render the paint water proof. Caustic soda takes away theacids of the different ingredients and adds materially to the strengthand elasticity of the paint. Asphalt-varnish helps to form a body to thepaint and at the same time is a good filler for the roofs. Turpentine isused as a partial thinner and also to cause the paint to dry morequickly. Ground asbestos, yellow ocher, Spanish whiting and wood ashesrender the paint fire, water and rust proof and add to the thickness orbody of the paint.

\Vhnt I claim is:

A paint composed of a mixture of the following ingredients in thefollowing proportions, coal tar fifty gallons, asphalt-varnish fivegallons, turpentine five gallons, ground asbestos fifteen pounds, yellowocher six pounds, Spanish whiting six pounds, water six gallons,screened wood ashes ten pounds and crude caustic soda two pounds;
